Micron Jumps 19% to Join $1 Trillion AI Memory Club
MU•Micron soared 19% on Tuesday, its largest one-day gain since 2011, pushing the company into the $1 trillion market-cap club alongside SK Hynix and Samsung as investors repriced the AI-memory sector. Analysts warn high-bandwidth memory shortages may last through 2027, bolstering Micron’s pricing power.
1. Market Cap Milestone
On May 26, Micron’s shares jumped 19%, the largest one-day gain since 2011, driving its market capitalization over $1 trillion. The surge followed a UBS analyst projection that Micron’s stock could double over the next year, reflecting investor enthusiasm for memory-chip stocks in the AI era.
2. AI Memory Demand Outlook
Industry forecasts indicate high-bandwidth memory shortages will persist through 2027 as AI data-center buildouts intensify. Counterpoint data shows Micron holds 21% of global HBM revenue share in Q4 2025, behind SK Hynix’s 57% and Samsung’s 22%, underpinning strong pricing power.
3. Risks and Catalysts
Volatility could arise from Micron’s planned ADR listing in the US and the launch of leveraged ETFs tied to memory suppliers. Any easing of supply constraints or a slowdown in AI capital spending may challenge the rally and temper expected earnings growth.
